WINDOW-FRAME.

Application filed October 1, 1915.

To all whom it may concern Be it known that I, HARRY S. Es'rnnn, a citizen of the United States, residing at Detroit, in the county of WVayne and State of Michigan, have invented a new and useful Window-Frame, of which the following is a specification.

This invention relates to the construction of metallic window sashes, particularly to those formed from rolled metal bars of standard form, and its object is to provide a sash which will be strong and of good ap pearance and which can be constructed with ordinary shoptools at comparatively low cost.

This invention consists in a novel joint between the frame members of a metal window sash described in the following specification and particularly pointed out in the claims.

In the accompanying drawing, Figure 1. is a rear elevation of a window sash embodying this invention. Fig. 2 is a perspective of a joint between two frame members the sash. Figs. 3 and a are perspectives of these two members before being assembled. Fig. 5 is a detail of the joint between a cross bar and one of the side bars.

Similar reference characters refer to like parts throughout the several views.

The cross bars and munnions of the sashes embodying this invention are preferably formed of rolled steel T bars consisting of webs and flanges, while the top, bottom and side members of the sashes may be of any desired cross section so long as they have webs at right angles to the planes of the sashes and inwardly extending flanges to support the panes of glass. In the present construction, all the frame members are shown to be of the same cross section, although this is not necessary.

The webs of the side bars 1 and 2 are suitably slotted to receive the reduced ends 3 of the webs 4: of the top bar 5, bottom bar 6, and intermediate cross bar 7, which may be riveted over to hold the parts together. Each of these bars is formed with flanges 8, those on the horizontal bars being shown cut away at their ends so as to form close joints with the flanges of the vertical bars.

The cross bar 7 and the munnion 9 are joined as illustrated in Figs. 2, 3 and i. The flanges 8 of the munnion 9 are sheared so that portions 10 thereof can be bent up,

after which the remainder of the flanges are cut away transversely sufficiently to admit the flanges of the frame member 7, the web lbeing formed with a notch 12 to receive the web of the frame member 7.

The web of the frame member 7 is formed with a notch bl to receive the remaining portion 15 of the web of the munnion S), and transverse notches 16 are cut in the flanges of this frame member 7 to receive the bentup portions 10 of the member 9, which should tightly fit the notches 16. If desired, the parts 10 may be secured in position by electric welding or by soldering with the oXy-acetylene flame after being bent down into the notches 16.

In order to temporarily secure the panes of glass in position, U shaped sheet metal clips 18 may be placed astraddle of the web at of the member 7 where the notches in are out .in. the flanges S, and also astraddle of all of the webs at the ends of the bars that are reduced to fit in proper holes in the side frame members, as shown in Figs. 3 and 5. After the sash is assembled, these clips will be held in position by means of the bent down portions 10 and by the flanges 8 of the exterior members of the sash. The ends of these clips can be easily bent over against the panes of glass and hold them in position until other retaining means have been positioned.

It will be understood that the construe tion, proportions and arrangements of the sash members may all be changed without departing from the spirit of my invention. as set forth in the following claims.

I claim 1. The combination of two flanged bars intersecting intermediate their ends, each having a comparatively thin web extending from both sides of the web of the other bar, one of the bars having a flange sheared to form a tongue free at one end and adapted to be bent up away from the bar and also formed with a transverse slot, the second bar being positioned with its web in the slot in the first bar and having a transverse slot in its flange to receive the tongue when bent back to original position.

2. The combination of sash bars, each comprising a flat web at right angles to the plane of the sash and lateral flanges, all the flanges of the sash bars being in the same plane, the flanges of one of the bars being notched transversely sufliciently to receive tongues constituting a portion of the other bar and the outer edge oi the Web of the first sash bar being notched to receive a portion of the web of the second bar the second bar having a pair of tongues free at one end constituting a portion of its lateral flanges and lying in the plane thereof in the notches in the flanges of the first bar and also having a notch in its web next to the plane of said flanges to receive the remainder of the Web of the first bar, the flanges of the second bar apart from said tongues being transversely notched to receive a portion of the flanges of the first bar 3. The combination of intersecting T bars having webs and lateral flanges, the flanges of all the bars being in the same plane, the flanges and web of one of the bars being notched transversely to receive edge portions of the flanges and a portion of the web of the second bar, the web of the second bar being notched to receive the Web of the first bar and the flanges oi the second bar being cut away intermediate the edges to receive a portion of the flanges ot the first bar, the remaining edge portions of the flanges of the second bar being attached at one end to the ren'iainder of the bar and extending into notches in the first bar.

l. The combination of intersecting flanged T bars, one 01" the bars having two parallel notches across its flanges and a notch across the web opposite the flanges to receive portions of the other bar, the flange portion of the second bar being cut away to receive the portion of the flanges of the first bar inter Copies of this patent may be obtained for five cents each, by addressinggthe Co nmissioner ofl -Patents i mediate the notches therein and having a notch across the Web next said cut away portion toreceiv'e the remainderof the Web of thefirst bar, allbf-the portions of the flanges being in one plane, and sheet metal clips of U form mounted in the notches in the first bar across its Web.

5. The combination of two intersecting flanged bars, each having its Web notched intermediate its ends to receive the Web of the other bar, the flanged portion of one bar be.- ing cut away entirely across along, the lines of theouter edges ofthe flanges ofthe second bar, and edge portions of the flanges of the second bar being sheared free-i to 'form tongues attached, at one: endaandextending into said notches entirely across the flanged portion of the first bar,- theflanges of the two bars lying in the sameplane, the tongues beingattached to the flanges otthesecond barfrom which they 2116 Sl162ll'..6d2&t opposite sides of the first bar,

6. The combination of intersecting flanged bars, one of said bars being notchedto receive the other bar, the flange portion ofh'the second bar also being notched,, a portion of the flange ofthe first bar extendinginto the notch in the flangev ofthe second bar, the flanges of the two bars lying. in'the. same plane, and a sheet inetalwclipi of U.-forn1 mounted in the notch ofthe second. baron its web and held in position by a portiomof the flange of the first ban, 7

In testimony whereof I sign this specification.
